From a lecture titled “Solitude and Leadership,” which William Deresiewicz delivered to the plebe class at the United States Military Academy at West Point in October 2009:
Thinking for yourself means finding yourself, finding your own reality. Here’s the other problem with Facebook and Twitter and even The New York Times. When you expose yourself to those things, especially in the constant way that people do now — older people as well as younger people — you are continuously bombarding yourself with a stream of other people’s thoughts. You are marinating yourself in the conventional wisdom. In other people’s reality: for others, not for yourself. You are creating a cacophony in which it is impossible to hear your own voice, whether it’s yourself you’re thinking about or anything else. That’s what Emerson meant when he said that “he who should inspire and lead his race must be defended from travelling with the souls of other men, from living, breathing, reading, and writing in the daily, time-worn yoke of their opinions.” Notice that he uses the word lead. Leadership means finding a new direction, not simply putting yourself at the front of the herd that’s heading toward the cliff.
So why is reading books any better than reading tweets or wall posts? Well, sometimes it isn’t. Sometimes, you need to put down your book, if only to think about what you’re reading, what you think about what you’re reading. But a book has two advantages over a tweet. First, the person who wrote it thought about it a lot more carefully. The book is the result of his solitude, his attempt to think for himself.
Second, most books are old. This is not a disadvantage: this is precisely what makes them valuable. They stand against the conventional wisdom of today simply because they’re not from today. Even if they merely reflect the conventional wisdom of their own day, they say something different from what you hear all the time. But the great books, the ones you find on a syllabus, the ones people have continued to read, don’t reflect the conventional wisdom of their day. They say things that have the permanent power to disrupt our habits of thought. They were revolutionary in their own time, and they are still revolutionary today.
